How to preload a SWF?

[LuisPedro]

I'm trying to make a preload of the main.swf from the preload.swf.

The preload.swf code is:
import flash.display.Loader;
import flash.display.LoaderInfo;
import flash.net.URLRequest;
import flash.events.Event;
import flash.events.ProgressEvent;
import flash.text.TextField;
import flash.display.MovieClip;

var myLoader:Loader = new Loader();
var myRequest:URLRequest = new URLRequest("main.swf");

myLoader.load(myRequest);

myLoader.contentLoaderInfo.addEventListener(Event. OPEN,showPreloader);
myLoader.contentLoaderInfo.addEventListener(Progre ssEvent.PROGRESS,showProgress);
myLoader.contentLoaderInfo.addEventListener(Event. COMPLETE,showLoadResult);

var loadProgress_txt:TextField = new TextField();

function showPreloader(evt:Event):void {
addChild(loadProgress_txt);
}

function showProgress(evt:ProgressEvent):void {
loadProgress_txt.text = "loaded:"+evt.bytesLoaded+" from "+evt.bytesTotal;
}

function showLoadResult(evt:Event):void {
removeChild(loadProgress_txt);
addChild(myLoader);
}

And it gives me this errror:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at main_fla::MainTimeline/main_fla::frame1()

The problem is that i don't know how to do this preload and copy that code from another page...

Can anyone helpe with this, or explain how to build a preload with a progress bar tha realy work?

Tnks in advance

Does your text field get added to the stage?

Try not making adding the text field dependent on the eventListener.


Also - what line of code is the error on (if any is given) - this looks like the type of error you get if you start refering to "stage" or "root" before items are added to the main timeline.

import flash.display.Loader;
import flash.display.LoaderInfo;
import flash.net.URLRequest;
import flash.events.Event;
import flash.events.ProgressEvent;
import flash.text.TextField;
import flash.display.MovieClip;

var myLoader:Loader = new Loader();
var myRequest:URLRequest = new URLRequest("main.swf");

myLoader.load(myRequest);

//myLoader.contentLoaderInfo.addEventListener(Event. OPEN,showPreloader);
myLoader.contentLoaderInfo.addEventListener(Progre ssEvent.PROGRESS,showProgress);
myLoader.contentLoaderInfo.addEventListener(Event. COMPLETE,showLoadResult);

var loadProgress_txt:TextField = new TextField();

//function showPreloader(evt:Event):void {
addChild(loadProgress_txt);
//}

function showProgress(evt:ProgressEvent):void {
loadProgress_txt.text = "loaded:"+evt.bytesLoaded+" from "+evt.bytesTotal;
}

function showLoadResult(evt:Event):void {
removeChild(loadProgress_txt);
addChild(myLoader);
}

Yes. The text field is added on the stage.
The erros is not in the ActionScript timeline but in the Erros on the Preview.

"TypeError: Error #1009: Cannot access a property or method of a null object reference.
at main_fla::MainTimeline/main_fla::frame1()"

Nikefido,, send you a PM.

I try the preload.swf code with a JPG file and it work fine.

Only when i change URLRequest() to any SWF file it brings me that error, so i think that is relater with the method I call it (addChild) or with the code in main.swf!!

I think that is the method i call it because maybe that's not possible to addChild with a SWF file...

Any sugestions?

[stompwampa]

no, addChild is exactly what you want...that's what I used in my preloaders...your code looks good though, so I'm not sure what the issue is...

did you uncheck the property to load the AS etc on frame 1?
There's an option for it, but I cannot currently remember where it is :(

I have to uncheck it all????
But if i do that the AS doesent recognize... :confused:

But i do that and when i test it, it became a lot of erros.

I don't think that is the solution.

Remember i don't have anything on stage, it's all became from the AS timeline.
